The model of a systems development life cycle provides for progressive development of operational software, with each release providing added capabilities. a. RAD life cycle b. incremental build life cycle c. waterfall life cycle d. spiral life cycle

B. Incremental Build life cycle

Explanation:

RAD life cycle: RAD model of software development life cycle is all about coming up with prototype as soon as possible. It describes a method of software development which heavily emphasizes rapid prototyping and iterative delivery.

Incremental build life cycle: In incremental build model of software development life cycle, each release of the software have added capabilities. The development is finished when the user is okay with the present features. Focus is put on creating a working prototype first and adding features in the development life cycle. This is the correct option.

Waterfall life cycle: In a waterfall model, each phase must be completed fully before the next phase can begin and this usually takes time before a working software can be released. There is also no overlapping in the phases.

Spiral life cycle: Spiral Model can be pretty costly to use and doesn't work well for small projects. It's a risk-driven model which means that the overall success of a project highly depends on the risks analysis phase.

Incremental Build Life Cycle

Explanation:

In the incremental build life cycle of software development, each software tat is released have added capabilities than the previous version. The development in this case is considered to be over and done once the user is satisfied with the current features and capabilities. The first step to achieving this model is via creating a prototype and then adding features during the development life cycle.
